MEMS oscillator suits 125C apps

Suited for industrial and high reliability
applications, the SiT8920 MEMS oscillator operates over the widest
temperature range of -55° to 125°C, consumes less
than 4 mA typ — half the power of quartz oscillators, is
twice as stable, 20x more reliable, and 30x more robust to shock
and vibration. Specifically the part features 0.1-ppb/g vibration
sensitivity, 50,000-g shock, and 70-g vibration resistance, 500
million hours MTBF (2 FIT) reliability, and ±25 ppm
stability over the operating temperature for better system
timing.

It includes a unique SoftEdge rise/fall time
control that reduces system EMI without additional components,
expensive shielding or PCB re-design. Also introduced with this
part are the SiT1618, a fixed-frequency oscillator that operates
over -40° to 125°C, and the SiT8918, a programmable
oscillator that operates over the same temperature range and
supports any frequency between 1 and 110 MHz as well as 1.8-V and
2.5 to 3.3-V operation. Five industry-standard package options are
available, including a tiny 2.0 x 1.6 mm, all of which are drop-in
replacements for quartz oscillators. (Contact company for pricing
